intelfb on 82852/855GM

Hello, 

I'm trying to get intelfb compiled into kernel 2.6.11(-gentoo-r5) with 

video=intelfb:1024x768-16@60 

in my grub.conf kernel command line to work with my fujitsu-siemens
lifebook (with intel 82852/855GM graphics) and keep getting the
following in dmesg:

intelfb: Framebuffer driver for Intel(R) 830M/845G/852GM/855GM/865G
chipsets
intelfb: Version 0.9.2
intelfb: 00:02.0: Intel(R) 855GM, aperture size 128MB, stolen memory
8060kB
intelfb: Non-CRT device is enabled ( LVDS port ).  Disabling mode
switching.
intelfb: Video mode must be programmed at boot time.

Needless to say, the fb doesn't work for me so far. I've also tried
other modes (theoretically, the system supports 1400x1050-24@60), but
with no success so far. (Research in Gentoo forums makes me think I'm
not the only person getting these error messages, but I didn't find
anything usable there.) Any help would be welcome, I'd help gladly with
testing fixes (if it's the driver's and not my fault). 

Greetings
themuse
